Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of an installation device for a blower installed underwater for the purpose of exhausting or blowing air, for example in water treatment equipment.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, there are many blowers that exhaust or blow air for the purpose of cooling and noise prevention, at least while the blower body is immersed in water.

However, the blower body must be removed from the tank from time to time for inspection, maintenance, lubricating oil changes, etc. In this case, for aeration in raw water tanks, only the tip of the suction pipe is made to protrude into the air, and the entire discharge pipe can be raised and lowered by an appropriate guide as a whole, but the suction and discharge pipes are fixed on land and the water tank In the case where it is necessary to perform suction and discharge between a separate place and a separate place, it is not possible to raise and lower the blower piping integrally, as in the case of the aeration system described above. That is, it is necessary to connect or disassemble the suction and discharge pipes on land.

In order to be suitable for this purpose, the present applicant has previously invented an installation device for a submersible blower as disclosed in Japanese Patent Application Laid-open No. 85405/1983. However, in this case, the suction and discharge pipes are installed in parallel with appropriate pitches on land on one side of the water tank, and the end on the blower side is opened upward, and the blower body is connected to the intermediate pipes. In addition to being guided for positioning by a lifting guide device fixed to the water tank wall, the tip of the intermediate pipe, which opens downward, is connected to the tip of the suction and discharge pipes on the fixed side through a cushion material that also serves as leak prevention. Because they were designed to fit against each other in the vertical direction, when several large blowers were arranged in parallel, a long water tank was required, which increased the installation space.Also, since the connection part was only dependent on the blower's own weight, it was difficult to install large blowers. However, small blowers have the disadvantage that the airtightness of the joints is not sufficient due to the lack of weight for the joints to abut.

[Means for solving problems]

The present invention differs from the prior art described above in that the suction and discharge piping is fixed on land and the blower body is submerged in water, and the ends of the suction and discharge piping on the blower side are connected to land at a predetermined interval by fixed connection pipes with mounting legs. The blower main body side is connected to the suction and discharge ports of the main body to form a U-shape as a whole, and one horizontal pipe with a partition wall and a hanging fitting in the center and the U-shape The horizontal tube is formed integrally with an intermediate piping assembly whose upper ends are connected in a continuous manner, and both ends of the horizontal tube can be freely attached to and detached from the blower side end of the suction/discharge piping via flexible rubber couplings. This invention relates to an installation device for a submersible blower, characterized in that the submersible blower is connected to the horizontal tube end, and further includes legs each having a cushion material on the lower surface near the end of the horizontal pipe so as to be grounded on the land surface.

[Effect]

The blower main body and the intermediate piping assembly are roughly positioned using a horizontal pipe with a constant distance between the open ends at both ends, and a cushion material provided on the leg provided near the end of the horizontal pipe and a cushion material provided on the horizontal pipe end. The rubber coupling prevents vibrations during blower operation from being transmitted to the land surface and suction/discharge piping.

〔Example〕

The embodiments shown in the drawings will be described in detail, and for convenience of explanation, the vertical direction in FIG. 1 will be referred to as the "vertical direction," the left-right direction will be referred to as the vertical direction, and the vertical direction in FIG. 2 will be referred to as the "horizontal direction."

In the figure, 1 is a suction pipe with a strainer 2, a muffler 3, and a fixed connection pipe 4 with a mounting leg, and 5 is a discharge pipe with a fixed connection pipe 6 with a mounting leg, and the fixed connection pipe 6 is equipped with a safety valve 7. The outer ends of both fixed connecting pipes 4 and 6 are arranged oppositely on the land surface 9 on both sides of the water tank 8 with a predetermined distance S between them.

10 is a blower body with a submersible motor, and intermediate pipes 11 and 12 are provided at the suction and discharge ports, respectively.
The intermediate piping is connected upward to form a U-shape as a whole, and the intermediate piping is connected in communication with one horizontal pipe 13 to form an intermediate piping assembly 14.
The horizontal pipe 13 can be suspended at the center by a hanging fitting 15 with a partition wall, and the inside of the horizontal pipe 13 is separated into two chambers, and flexible rubber couplings 16 are bolted to both ends. There is. Further, the length of the horizontal pipe 13 is determined so that the total length with the rubber coupling 16 attached almost matches the distance S between the outer ends of the fixed connecting pipes 4 and 6. Further, a leg portion 18 having a cushion material 17 on the lower surface is attached near the end of the horizontal pipe 13, and the blower main body 10 and the intermediate piping assembly 14 are integrated by grounding the cushion material 17 to the land surface 9. It is designed to support things.

Both fixed connecting pipes 4, 6 and rubber coupling 1
6 can be connected in a one-touch manner without the need for bolts or the like by engaging the fasteners attached to both sides of the fixed connecting pipes 4 and 6 and the receivers embedded in the rubber coupling 16 side. Defection is becoming possible.

Therefore, in order to connect the blower main body 10 and the intermediate piping assembly 14 to the suction piping 1 and the discharge piping 5, the hanging fitting 15 with the bulkhead is suspended by a chain block or the like to connect the two pipings 1 and 5. When lowered, the integral body is supported on the land surface 9 by the cushion members 17 and approximately positioned. Next, by operating the fasteners attached to the fixed connecting pipes 4, 6 and connecting them to the rubber coupling 16, the installation is completed.

At this time, the intermediate piping assembly 14 is connected to the horizontal pipe 13.
Since the length in the vertical direction is constant, the distance between the end faces of both rubber couplings 16, 16 is also almost constant and almost matches the end face distance S of the fixed connecting pipe, and there are some differences in the vertical and horizontal directions. Misalignment is corrected by the flexible rubber couplings 16, 16, making it extremely easy to create a secure connection without leakage. Moreover, to lift the blower main body 10, it is only necessary to remove the stopper in the reverse direction and lift the hanging fitting 15 with the partition wall.

During operation, vibrations on the blower side are absorbed by the cushion materials 17, 17, and together with the presence of the rubber couplings 16, 16, vibrations are transmitted not only to the land surface 9 but also to the suction pipe 1 and discharge pipe 5 side. does not occur.

[Effect of idea]

Since the present invention has the above-mentioned configuration, the dimensions between both ends of the intermediate piping are almost constant, so installation can be performed accurately and with sufficient capacity.In addition, installation and removal are extremely easy as troublesome operations such as attaching and removing bolts are not required. Not only can this be done easily, but since the arrangement is well-balanced both vertically and horizontally, vibrations caused by unbalanced loads during operation do not occur, and vibrations caused by the pulsation of the blower itself are suppressed by the cushion material and rubber cup. It is expected that quiet operation will be achieved because the ring absorbs and blocks the noise, preventing it from being transmitted to the land surface or suction/discharge piping.
